Description

  2. Fill in OS details, select Image Based provisioning method
  3. Click Resolve (templates) button

This results in a server error and "Sorry but no templates were configured":

It appears that host_params is called multiple times in the controller's template_used method, and only includes compute_attributes on the first call (keep_param deletes it from the source params hash).
